Description Groundwater is the primary source of drinking water for over 56,000 residents in the Lower Yakima Valley. Elevated concentrations of nitrate have been found in drinking water in some areas. Nitrate contamination can cause health problems. This project will measure groundwater nitrate concentrations as the community works to reduce nitrate sources.

Department of Ecology scientists will sample 170 wells across the Lower Yakima Valley to determine nitrate concentrations and to measure them over time. Beginning in July 2021, we will collect well-water samples every three months for two years, and then annually. Sampling your well water is the best way for us to determine if there are problems in the groundwater.

This study is part of a larger legislatively funded effort to reduce nitrate concentrations in groundwater to meet drinking water standards in the Lower Yakima Valley. A local groundwater management area (GWMA) group has been working to reduce nitrate concentrations to ensure drinking water is clean and safe. This GWMA group consists of Yakima County, Yakima Health District, South Yakima Conservation District, Washington State Department of Ecology, other state and federal agencies, farmers, livestock producers, environmentalists, and concerned residents.
